SAWING-IvZACI-IINE Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed September 3, 1907. Serial N 0. 391,076.

To all whom it may concern:

Be it known that I, JOHN J. MEYnRs, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sawing-Machines, of which the following is a specification.

My invention relates to sawing machines ordinarily adapted in practice to carry a cirl0 cular saw-blade for cross-cutting purposes and a rip-saw blade for rip-sawing purposes, and so arranged as to adjust either saw-blade into position of use adjacent to the table.

It is the object of my invention to mount these saw-blades in novel manner and to provide other improvements in a machine of this character, all of which will more fully appear in the following specification and claims, and in the drawings, in which latter- Figure 1 represents a side elevation of my improved device. Fig. 2 is a front elevation thereof. Fig. 3 is a vertical cross-section of the same on the line .2-z of Fig. 1. Fig. 4 is a longitudinal section of the table, showing its connections, on the line g of Fig. 3. Fig. 5 is a vertical section on the line :ra: of Fig. 3; and, Fig. 6 is a detail in section on the line 'v'v of Fig. 1.

1 represents the main frame.

2 is an arbor-frame, at the respective ends of which are bearings 3 3 4 4. A shaft 5 is journaled in the bearings 3 and a shaft 6 is j ournaled in the bearings 4, these shafts constituting saw-arbors respectively adapted to carry saw-blades 7 8, the saw-blades 7 being shovm as a cross-cut saw-blade and the sawblade 8 being shown as a rip-saw blade.

The arbor-frame comprises a plate 9, which may be termed a turn-plate. I have shown the plate 9 as a separate plate attached to the arbor frame by means of bolts 10. The plate is located at an opening 11 at the side of the main frame, provided for the purpose of permitting the saw-arbors to overhang the 4 side of the main frame and to provide space for the turning of the arbors and saw-supporting frame about the axis of said frame, and the plate 9 is so located as to close this opening or form a cover therefor for the purpose of arresting the passage of saw-dust and the like through the opening 11. It will be noted that the saw-blades are located outside of the plate. These blades are respectively shown as secured to the arbors by clamps 12, the saw-clamps being shown as overhanging the plate to the outside thereof. The plate has a bearing in the main frame.

It is shown as having an annular bearing surface 13 at its periphery which has sliding connection with the circular slide-way 14 at the opening in the main frame, segment clips 15 being bolted to the main frame by bolts 16 for retaining the plate in position. The arbor-frame has a stud 19 received in a bearing 20 of the plate for centering the same with relation to the plate, and a stud 21 received in a bearing 22 secured at the back of the main frame. In the form shown the plate is provided with an opening 23 adapted to receive the front bearing 3 and an opening 24 adapted to receive the front bearing 4. The arbor-frame with its plate is adapted to be oscillated or turned in the bearing 22 and the slide-way 14 the rocking axes of the arbor-frame and its plate being maintained in true line.

The arbor 5 is provided with a pulley 25 and the arbor 6 is provided with a pulley 26 for turning the respective arbors by means of a belt receiving power from a suitable source and preferably arranged to pass from the left of the machine shown in Fig. 1, under a pulley 29, thence over either of the pulleys 25 or 26, depending on which of the arbors is in operative position, and thence under a pulley 30 from the right of said pulley shown in Fig. 1 and back to the source of power the stretch of said belt between said pulley 30 and said source of power being under but distanced from said pulley 29. The pulleys 29 30 are mounted on a swingingframe 31 pivoted on a rod 32 to the main frame.

For turning the arbor-frame I provide the arbor-frame with a worm-wheel 35 with which a worm 36 meshes, the worm being on a shaft 37 j ournaled in bearings 38 and having a hand-wheel 39 thereon for turning the same. The arbor-frame within its mounting and operating parts may be so arranged as to turn the arbor-frame in one direction or it may be arranged for turning the same only parts of a revolution in reverse directions for bringing the respective saw-arbors into operative position adjacent the table. For preventing injury to the operator, the front part of the frame at its side adjacent the sawblade is provided with a protecting hood 40.

41 is a table which is shown mounted so that the same may be placed at an angle with relation to the saw-blade, as by providing the same with arc-pieces 42 supported in arc bearings 43 on the main frame.

44 is a link articulated with the table at 45 and with an arm 46 at 47, the arm being rigidly secured to a shaft 48 mounted in bearings 49 of the main frame and having thereon a worm-wheel 50 with which a worm 51 meshes, the Worm being on a shaft 52 journaled in bearings 53 in the frame and having a hand-wheel 54 thereon. The table is provided with a depending rib 55 having a recess 56 for accommodating the upper edge of the plate 9.

58 is a longitudinally movable or slidable table which is sup orted by the shelf 59 of the table-frame. lilpon the shelf there is a table-saddle 60 which is shown secured to the shelf by means of bolts 61 passing through slots 62 in the saddle and into the shelf, this permitting adjustment of the sliding table toward and from the saw-blade. Guide-ways 63 are adjustable on the saddle adjacent to the sides thereof by means of bolts 64 threaded into the saddle and taking against the undersides of the guide-ways. These guide-ways extend longitudinally of the slidable table, there being a plurality of the bolts distributed lengthwise of each of the guide-ways for adjusting the same at various points. Bolts 65 pass through slots 66 in the guide-ways and into the saddle for clamping the guideways in adjusted positions.

67 is a roller-frame having rollers 68 on shafts 69 in bearings 70 in the roller-frame. The said roller-frame is located and operates between the saddle and the movable table 58, serving as an anti-friction slide for said table. The roller-frame is of less length than the guide-way for permitting the same to roll between the guide-ways and the movable table. The movable table has a limiting lug 71 thereon adapted to slide against the slide-way 72 on the saddle 60, and also has a flange 73 mating the slide-way 74 on the saddle. The movable table is adapted to be moved by a handle 75.

It is desirable to lock the movable table in position, and I provide means for this purpose which may be instantly released, as by providing the movable table with a slot 76 receiving a finger 77 on a lever 78 pivoted to the saddle at 79 and having a weighted handle 80, the lowering of the handle permitting the finger to move into the slot for locking the movable table, the movable table being released by the raising of said handle.

My improved device is especially applicable for use in pattern-work for making patterns for castings or other work in which it is desired to use both a rip-saw-blade and a cross-cut saw-blade and to rapidly change from one to the other.

My improved construction further permits the saw-blades to be over-hangingly mounted, that is to say, the saw-flanges are at the ends of the arbors, outside the frame, and the saw-blades may be conveniently re moved or replaced. The construction further provides rigidity, as the bearings are closely adjacent the saw-blades, and it further provides a closed frame within which the bearings and driving devices for the sawarbors are located.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:
